Summary

Exception handling can be attached to the definition of procedures and data objects. It supersedes the object's definition when the object fails. With procedures, this provides default exception handling for all invocations of the procedure. With data objects, it provides responses to range failure and other data inconsistencies. (cbb 5/80)
